I have not been able to reproduce this issue yet. I am using the same Comet
commit and so far have tested on a single node cluster with these configs:
```
$SPARK_HOME/bin/spark-submit \
--master $SPARK_MASTER \
--conf spark.driver.memory=8G \
--conf spark.executor.instances=2 \
--conf spark.executor.memory=30719m \
--conf spark.executor.memoryOverheadFactor=0.6 \
--conf spark.comet.memory.overhead.factor=0.04 \
--conf spark.executor.cores=6 \
--conf spark.cores.max=12 \
--conf spark.eventLog.enabled=true \
--jars $COMET_JAR \
--driver-class-path $COMET_JAR \
--conf spark.driver.extraClassPath=$COMET_JAR \
--conf spark.executor.extraClassPath=$COMET_JAR \
--conf spark.sql.extensions=org.apache.comet.CometSparkSessionExtensions
\
--conf spark.comet.enabled=true \
--conf spark.comet.exec.enabled=true \
--conf spark.comet.exec.shuffle.enabled=true \
--conf spark.comet.exec.shuffle.mode=auto \
--conf
spark.shuffle.manager=org.apache.spark.sql.comet.execution.shuffle.CometShuffleManager
\
tpcbench.py \
--name comet \
--benchmark tpch \
--data /mnt/bigdata/tpch/sf1000/ \
--queries /home/andy/git/apache/datafusion-benchmarks/tpch/queries \
--output . \
--iterations 1
```
The query completes:
```
Query 5 returned 5 rows
Query 5 took 456.6006717681885 seconds
```
I am going to test on a two node k8s cluster next.
